To all when it may concern/.-

Be it known that I, CARL RUDOLPH scription.

My invention relates to siphon-collars, my more particular object being to provide a two-part collar so arranged as to distribute mechanical strains upon the bottle-neck to better advantage, thereby avoiding any danger of breaking.

Reference is to be had'to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding par-ts in both figures.

Figure 1 is a fragmentary elevation, partly in section, showing the upper end of a bottle provided with a siphon of ordinary construction connected thereto by means of myimproved siphon-collar; and Fig. 2 is a perspective view of the two halves of the collar separated from each other.

The body of the bottle is shown at 3 and is provided with a frusto-conical neck 1, having an annular bead 5 encircling the same and integral therewith. The two halves or members 6, together constituting the collar, are each provided internally with an arcuate groove 7 and externally with a flange 8. Each half 6 is provided externally with a thread 9. A cap 10, of metal, threaded internally, as shown, screws upon the thread 9 and forces a gasket 11 downwardly upon the top of the bottleneck, as indicated in Fig. 1. A valve 12, mounted upon a valve-stem 13 and retained in normal position by a spring 14, is of the usual construction. The siphonhead is shown at 15, and the movable handle at 16. The latter is used for moving the valve-stem 13, thereby opening the valve 12. The spout is shown at 17 and is of the usual construction.

I find that in siphons of the kind heretofore used the collar beingmounted at a comparatively high point upon the bottle-neck exerts a considerable strain upon the neck and is liable to cause the latter to break whenever the apparatus is subjected to any considerable jar. Upon this account I locate the annular bead 5 at a little distance from the upper end of the frustoconical neck 4.. The two halves 6 are placed in juxtapo sition upon opposite sides of the neck, the arcuate groove 7 in each half fitting neatly upon a portion of the annular bead 5. The two halves may for convenience be gripped in a vise until the cap 10 is screwed into position. This being done, the two halves may receive no further attention. The pressure exerted upon the threads 9 by the cap 10-is such as to prevent the displacement of the two halves 6, for the reason that neither groove 7 can leave its portion of the bead5.

The upper end of the body 3 where it merges into the lower end of the frusto-conical neck 4 is nearly always made of comparatively thick glass, and being a small distance away from any part presenting an edge its annealing is nearly always better. Upon this account it is much more difficult, other things being equal, to break a bottle-neck at the point represented by the annular bead 5. The bead itself though integral with the bottle-neck serves to some extent as an encircling band and still further strengthens the neck at this point. The two-part siphon-collar by distributing the strain not only upon the annular bead 5, but also in a measure throughout the substance of the glass immediately adjacent thereto, prevents the possibility of undue breakage in case any part of the apparatus should receive a jar or blow.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a device of the character described, the combination of a siphon-collar made in halves, each half being provided internally near its bottom with an arcuate groove for engaging an annular bead upon a bottle, each half being further provided with a thread and with an annular bead intermediate of said thread and the approximate position of said arcuate groove, and a siphon-head provided with a cap threaded internally for the purpose of engaging the threads of said halves.

2. A device of the character described, comprising a siphon-collar made in halves, each half being provided internally adjacent to its lower edge with an arcuate groove for engaging a bead upon a bottle, and being Ice provided externally with a semicircular bead In testimony whereof I have signed my and With a semicircular shoulder bounding name to this specification in the presence of said bead, each of said halves being provided two subscribing Witnesses.
